This research  is aimed to use extracted  substances  from sawdust  of ulin for meubet coating.  Extraction and fractionation  used the solvent of methanol,  n hexan, diethyl ether, ethyl ace tat and hot water with the concentration  of 1 %, 2 %, 4 % and      % respectively.   The meubel  Is made  of rubber  wood.  By application  of the meubel  will increase.  The highesl  yield of fractination  was achieved by 51,05 % of ethyl acetate and it will inhibit the growth of fungi about 89,09 %. The result of phytochemical   test showed  thai the solvent  of dlethyl ether  and  ethyl  acetate  can  isolate  the  most  of  bioactive  compound   like alkanoid, saponin, tripenoid and flavonoid.  These bioactive compound   gives cotor  appearence   and  durability   to  the  coaling  product.   The  results  also showed  that  the bigger  concentration   resulted  in  the bigger  retention  and pene/ratlon   of the extract.  In case  of extraction  with hot water and  2 % of concentrate gave maximum retention and penetration  of 4 %.
